SCLEROCEPHALUS Temnospondyli-Archegosauroidea-Actinodontidae
Below: pictures of temnospondyl partial larval skeletons that could belong to Sclerocephalus or Cheliderpeton on the basis of poor state of ossification of neural archs and ribs, small orbit, prefrontal and postfrontal in contact, massive clavicles and rhomboidal interclavicle with regular dermal ornamentation. It is more probably that it is a Sclerocephalus than a Cheliderpeton, because they were collected in an area extremely rich of Slerocephalus. From Odernheim, Upper Part of the Lower Rotliegend, Saar Nahe Basin - Germany. Lower Permian. 2) Sclerocephalus: enlarged picture of the skull of the same skeleton 3) Sclerocephalus: pectoral girdle of a second skeleton
